Abstract: 123,367. Aston, A. E. Feb. 12, 1918. Portable buildings.-A floor of juxtaposed sections D, Fig. 51, being provided, wall sections A, B, C, C', C<2>, and H' are set up thereon to constitute, with roof sections E, a cubicle, row of cubicles, or a long room. Two such rows or rooms being erected, the passage between them is covered by roof sections G laid at right-angles to the sloping sections E. The sections A, B of the outer walls are wooden frames covered outside by overlapping sheets of corrugated iron with or without intervening canvas, and they are fixed to the floors and attached in contact to each other by bolts at allotted holes f. The sections of the roof are similar frames. The sections C<2> of the opposite walls, which will also be outer walls if only one row of cubicles is erected, are somewhat taller, and are covered outside by planks which project at top and bottom. The sections C, C' of the end walls or partitions are frames covered with planks ending flush. The outer uprights of the partitions are furnished with eyes C which register with holes f in the sections A, B, C<2> of the main walls and take bolts. The top members of all the wall sections are furnished with central eyes c, and the ends and sides of the roof sections E or G have corresponding holes. Figs. 52, 53, and 54 show the joints at the eaves, corner, and verge respectively. The requisite windows and doorways with or without lights or louvers thereover are incorporated in the sections. Doorway-sections are provided for the ends of the passage, and these may be used between the partition sections C' with removal of the inner walls C<2> so as to widen a cubicle or combine two into a larger one. As this removal leaves a gap between the adjacent uprights of the partition and the doorway section, a filler, Fig. 50, is provided. Alternatively, with removal of the inner walls C<2>, the sections C' may be replaced by sections k, Fig. 35. Also either the passage or one row of cubicles may be omitted. Further, the partitions may be omitted and the roof sections may be supported by a truss, Fig. 49, which is made of folding parts for easy packing. Lastly, a top light in sections is provided to take the place of a roof section of the passage or gangway.

Title: Improvements in or relating to the production of photographic images by a migratory reversal transfer process
Inventor: PHILLIPS HENRY
IPC: G03C8/24
Filed: 1951-02-02
Abstract: 706,333. Photographic positive production by migratory transfer. ILFORD, Ltd. Jan. 29, 1952 [Feb. 2, 1951], No. 2588/51. Class 98(2) A latent image is formed in a light-sensitive silver chloride material and developed in presence of a silver chloride solvent and benztriazole or a derivative thereof containing one or more alkyl, aryl, aralkyl, amino, halogen, substituted amino; nitro or alkoxy substituents or doubly linked benz groups in the benzene ring, while the material is in contact with a receptive colloid layer carried on a support. A black or blackish blue positive image is thereby obtained in the receptive layer as compared with a brownish image obtained without use of the triazole compound. Benztriazole or its derivative may be present in the developer or the receptive layer or both. The silver chloride layer and the receptive layer may be on separate supports, squeezed together and peeled apart after development, or a single support may carry both layers with removal of the silver chloride layer by hot water washing when unhardened gelatin is used as binder, or removal by stripping if an intermediate stripping layer is present, to leave the visible positive image. The receptive layer may contain all the development substances, thus in the example it is constituted by a paper support coated with a composition comprising gelatin, benztriazole, colloidal lead selenide, hydroquinone, sodium sulphite and thiosulphate, and this is soaked in a solution containing sodium carbonate and sodium sulphite, contacted with an exposed silver chloride printing paper for two minutes and then separated to provide a negative record in the printing paper and a positive in the receptive'layer. 5- or 6-chlorobenztriazole may be used in smaller quantity.than benztriazole to produce the same result. Specifications 614,155, 654,630, 654,631 and 684,641 are referred to.

Title: Improvements in or relating to power transmission
IPC: B60K17/10
Filed: 1924-02-02
Abstract: 211,853. Jackson, W. J. Mellersh-, (Reece Transmission Co.). Feb. 2, 1924. Variable-speed gearing is rendered automatic by the action of vanes 46 upon planetary centrifugal masses 47, which may consist of steel balls in oil, of mercury, or of another liquid. The masses 47 are carried in annular chambers 45 group-supported so as to turn loosely upon spindles 12, Fig. 1, upon a disc 11 secured to a driving-shalt 10. The masses 47 do not pass over the vanes. A mass 47 in its outward position shown in Fig. 5, on being picked up by a vane 46, is heaped up against the vane as shown in Fig. 6, so that its centre of mass is nearer the centre of rotation. Each group 35 of chambers is fixed to a gear 55 which is connected through planetary idlers 57, 58 to a gear 25 secured to the driven shaft 20. The chambers are thus driven in the opposite direction by the resistance of the shaft 20. Difference in speed between the shafts 10, 20 is resisted by centrifugal action in the chambers which is automatic and elastic and ineffective at low speeds. Thus in the application to a vehicle, throttling down the engine has the effect of declutching. Reversed driving is effected by braking a drum 62 which is secured to a sun gear 60 meshing with the gears 57. There are transverse channels 49 between the chambers 45 of each group to equalize amounts of inertia matter. pecification 225,735 is referred to.

Filed: 1942-03-03
Abstract: 549,568. Type-bar-making machines. MERGENTHALER LINOTYPE CO. March 3, 1942. No. 2804. Convention date, July 10, 1941. [Class 100 (iii)] Assembling matrices. To prevent the leading matrix of a line from falling over during the rise of the assembler, it is frictionally supported by a pivoted gate 22, which extends along the front of the assembler, and is held'out of action during composition of the line, but moves rearwardly to engage the leading matrix when the assembler rises. The inner wall of the gate is tapered, so that it approaches more nearly to the opposite wall of the assembler as the distance from the entrance end increases. In the lower position of the assembler, the gate is held forwardly by a fixed cam-plate 32 against the pressure of a spring 34. When the assembler rises, the gate escapes from the cam-plate and is pressed against the upper ear of the leading matrix, which is thereby supported independently of the position of the long finger of the line-delivery slide.

Title: Waveform generator
Inventor: PRIOR HECTOR THOMAS
IPC: G06G7/28
Filed: 1965-01-22
Abstract: 1,036,053. Wave-form generator. STANDARD TELEPHONES & CABLES Ltd. Jan. 22, 1965, No. 2889/65. Addition to 982,824. Heading H4R. [Also in Division G4] A waveform generator of the kind described in the parent Specification has plural ring counters S 1 to S m in tandem switched on sequentially by a train of clock pulses of frequency m/T at terminal A; the frequency being M/T where m is the number of ring counter stages and T the time for a complete traversal and the counter recycling continuously. The outputs of the counter stages are connected to respective conductors V 1  to V M  and a set of conductors H 1  to Hk extend at right-angles thereto; the intersections being connected together by adjustable elements R, e.g. resistors, potentiometers, attenuators, or amplifiers preset so that any required fraction of the signal on a ring conductor V is transferable to any conductor H. The variable area pulses from the ring counter stages combine to develop stepped approximations to sinusoids on the horizontal conductors, which develop a train of frequencies harmonically related to a fundamental f 0 . It is shown that the frequencies thereof are mutually independent, provided that an integral number of waves are generated during each complete traverse of the counter, and that the clock frequency must be at least 2 x the highest required frequency and that the number of stages must be ¢ that frequency. Since even harmonics of the fundamental produce identical wave patterns in the first and second halves of the ring counter (Fig. 2a, not shown) and odd harmonics produce wave patterns in the second half which are inversions of those in the first half (Fig. 2b, not shown) the number of ring counter stages may be halved by adjusting elements R so that conductors H 1  to Hk develop desired whole numbers of carrier half-waves, inserting clock pulse filters in series with conductors H 1 , H 3 , H 5  etc.; developing signals comprising an even number of halfwaves, and inserting inverters in series with conductors H 2 , H 4 , H 6 &c. developing signals comprising an odd number of half-waves; the inverters being reversed at the end of each traverse of the ring counter by a signal from the clock pulse train or from a divider operated from a stage of the counter (Fig. 3, not shown). The apparatus is stated to be applicable to the generation of harmonically related carrier frequencies for multiplex telecommunication systems.

Title: Transmission systems
IPC: H04L5/24
Filed: 1966-01-21
Abstract: 1,130,350. Telegraphy. HASLER A.G. 21 Jan., 1966 [21 Jan., 1965], No. 2959/66. Heading H4P. A multiplex system comprises a number of teleprinter subscribers, each having an identical local circuit, which are connectable by multi-pin plug and socket connectors to a time-division multiplexing transceiver. The time slots available in the multiplex cycle are allotted to the subscribers in dependence upon the number of subscribers currently connected to the transceiver. The embodiment described employs four subscribers and so the cycle contains four time slots, t1-t4. The transceiver has four connectors, A-D, and each may be connected to any of the subscribers, but must be used in the order A; A, B; A, B, C; A, B, C, D, depending on whether one, two, three, or four subscribers are connected to the transceiver. If only one subscriber is connected it transmits (and receives) during slots  t1-t4; if two subscribers are connected they transmit during t1 and t3, and t2 and t4, respectively; if three subscribers, during t2 and t4, tl, and t3, respectively; and if four subscribers, during t1, t2, t3, and t4, respectively. The connectors are so wired that the appropriate reallocation of the time slots among the subscribers occurs as a consequence of connecting a subscriber to the transceiver. The grouping can be varied, when less than four subscribers are connected, by shorting certain pins in the unused connector.

Abstract: 1,075,031. Power amplifiers. MATTES ELECTRONICS Inc. Jan. 25, 1965 [Feb. 12, 1964], No. 3211/65. Heading H3T. - A power amplifier adapted to be substantially free of cross-over distortion comprises a power-limited driver amplifier, arranged to deliver to a load a low-power signal substantially free of cross-over distortion and a power amplifier arranged to deliver to the load a second comparatively high-power signal corresponding to the input signal except for the presence of cross-over distortion. In the amplifier shown the input signal applied at terminal 50 is amplified by transistors 58-60, 65-67 and fed to the push-pull pair of transistors 71-73, 74-76 which feed the primary 94 of a transformer and also transistor 111-113. The action of transistor 111-113 as well as the voltage divider formed by resistors 81, 83 serves to limit the output power of the driver amplifier. Diodes 91, 117 act to block the action of transistor 111-113 after the power amplifier has become fully operative, and with transistor 111-113 act as a delay to maintain the outputs from the driver and power amplifiers in phase. The secondaries 94S 1 , 94S 2  of the transformer apply the signal to the push-pull power amplifier formed by transistors 122-124, 125-127 which apply the signal to the load 11 in combination with the signal from the driver amplifier so that the two signals are added such that the signal from the driver amplifier exactly compensates for the zero output of the power amplifier due to cross-over distortion (Fig. 2, not shown). Negative feedback loops formed by resistor 104 with capacitor 93 and resistor 105 in parallel with capacitor 106 are provided. It is stated that the power amplifier acts as a negative impedance device connected to the output of the driver amplifier.
